My understanding is that if it is a non-blocking call (which in the
case of the Spread library it should be as far as I know) then the call
should not return with a partial write.
I remember that some very old Linux version had a bug in this regards which
I pointed to Don Becker and he fixed, but that was many years ago.
So, in my opinion, if a partial write occurs on a blocking call
then that is a bug in the OS. What am I missing?
